The project’s expansion will involve testing a new floating solar technology, comprising a hydro-elastic membrane that serves to support PV modules.
Comprising a two-millimeter-thick reinforced hydro-elastic membrane, the new structure provides the foundation for 770 PV modules. This membrane incorporates a proprietary mooring and anchoring system, enhancing its flexibility and durability against intense waves and wind.
According to Acciona, the floating solar system is adaptable for deployment in reservoirs, marshes, and also marine environments. These PV modules are fixed at a 0º angle to bypass the impact of strong winds and prevent any potential “sail effect.”
The new module follows five adjoining floating systems, where the company is assessing the behavior and efficacy of various floating solar solutions.
The Sierra Brava floating solar plant started operating in July 2020, becoming the first grid-connected floating PV facility in Spain. According to Acciona, it is an experimental hub for testing different floating technologies in a real environment, and to gain knowledge in construction, operation and maintenance, and environmental monitoring.
The pilot floating solar plant now comprises 3,770 PV modules covering an area of over 12,000 square meters.
Acciona Energía’s pilot project at Sierra Brava includes environmental monitoring programs, focused on bird protection and interaction with floating solar facilities. Measures such as installing two floating platforms to encourage the reproduction of bird species, and placing 20 nesting boxes for them, aim to conserve local fauna.
